I have always preferred working on concrete problems rather than abstract theories.

Truth is like a blanket that always leaves your feet cold. You push it, stretch it, it'll never be enough. You kick at it, beat it, it'll never cover any of us. From the moment we enter crying to the moment we leave dying, it will just cover your face as you wail and cry and scream。

A good book is an event in my life.

最重要的是能够思考，能够观察，能够判断你所看到的事物。
